Draw graphs in VBscript

I have a HTML application, partially HTML, partially VBscript, disguised as a form. What it does is it opens a few local files, runs a DOS box containing GAWK and presents a text file as its result. I wish to expand upon it by letting it create a bitmap image with the results in a stacked bar graph, for instance as a .BMP file. But I'm stumped. I haven't the faintest idea where to start.

Well, in 2022 an answer could be to build from scratch an html file with svg commands then open it in the default browser.

The Microsoft Scripting Guys came out with an article which discussed his quite a while ago, but it involves using the Excel ActiveX control or the OWC control the article is really detailed in how to do it, look here: http://www.microsoft.com/technet/scriptcenter/topics/activex/chart.mspx

I believe you will be able to use this library http://www.walterzorn.com/jsgraphics/jsgraphics_e.htm in VBScript too. It can be used to draw all kinds of shapes lines, rectangles, circles etc

Once you have drawn the graph you can print the page to a PDF printer (like cutePDF) to get the image onto a file for later use.

Graphics are beyond the capabilities of VBScript alone. You can try if you find an ActiveX/COM component that can do it for you. Looking into Google, my guess is that most of them come as dumbed-down trial versions of quite expensive commercial products. Maybe someone else here knows one that is for free.

As an alternative route, you could set up a web service somewhere that does the image processing (for example PHP/gdlib) using URL parameters. Then you would just have to link to the image in your HTA with an <img> tag like you normally would.

Is javascript an option? That would be a lot easier than creating an image file.

I have used this jquery plugin http://code.google.com/p/flot/ a few times and works well.

I have not used VBScript for a few years now, think you would probably need to use an active-x object of some kind to generate an image file, but I could be wrong there.
